摘要： A solenoid plunger 14 of the switch 4 is moved by cam plunger 34 and is biased towards the cam plunger 34, a locking plate 40b is positioned between the plungers 14 and 34. Cam 34 is biased for movement towards a cam 22 and is moved towards the solenoid plunger by rotation of the cam 22 by removal of actuator 8 which causes retraction of the solenoid plunger into the switch 4. The locking plate 40b is lockable when the cam plunger 34 is biased into a detent 36 in the cam 22 when the actuator is inserted, to lock the cam plunger 34 and cam 22 and prevent removal of the actuator 8.

摘要： A position switch is disclosed with a device to generate a magnetic force, with at least a first coil and at least one armature, it being possible to magnetize and move the armature via the first coil. How the magnetic force, particularly at the start of movement of the movable components of the device, can be increased to reduce the necessary power consumption of the first coil, is a focus of at least one embodiment. For this purpose, at least one embodiment of the device to generate a magnetic force includes at least one device to premagnetize the armature. The result includes a series of advantages, e.g. a smaller design, lower power consumption and possible use with multiple different switching units with different counterforces.

摘要： A safety switch is provided which is increased in durability and which offers a high degree of freedom of mounting the safety switch to place.A switch body has a rectangular solid shape. An actuator entrance hole is formed at one of the opposite corner portions of the switch body whereas a cable lead-out port is formed at the other corner portion, whereby the safety switch is increased in the degree of mounting freedom. Thus is offered a wider choice of place to mount the safety switch. The switch body is formed with only one actuator entrance hole so that the safety switch is prevented from suffering failure caused by foreign substances invading through an actuator entrance hole left unused. In addition, a driving cam may be formed with an engaging portion and a cam curve portion in spaced relation so that the driving cam is configured to be free from an area having poor strength. Thus, the driving cam is increased in strength. This leads to the increased durability of the safety switch.
摘要翻译：提供了一种安全开关，其增加了耐用性，并且提供了将安全开关安装到位的高度自由度。开关体具有矩形的实心形状。致动器入口孔形成在开关体的相对的拐角部分的一个处，而在另一个拐角处形成电缆引出口，由此安全开关的安装自由度增加。因此，可以提供更多选择安装安全开关的位置。开关体仅形成有一个致动器入口孔，从而防止安全开关因留下未使用的致动器入口侵入的异物而引起故障。此外，驱动凸轮可以形成有间隔开的接合部分和凸轮曲线部分，使得驱动凸轮被构造成不具有较差强度的区域。因此，驱动凸轮的强度增加。这导致安全开关的耐久性提高。

摘要： A safety switch assembly for use with a machinery guard enclosing kinetic machinery, comprises a housing, an electrical contact arrangement and a rotatable actuator cam contained within the homing for operating the electrical contact arrangement and spaced from the electrical contact arrangement. Radial pockets are formed in the actuator cam and extend inwardly of the periphery of the latter. An axially-movable rod connects the electrical contact arrangement and the actuator cam to operate the former in accordance with rotational movement of the latter. The housing defines at least one entry adjacent the actuator cam for insertion of an actuator into the housing to engage the radial pockets to rotate the actuator cam. Anti-rotational locking means releasably engage the actuator cam to prevent rotation of the latter and consequent operation of the electrical contact arrangement until a separation of the actuator cam and the anti-rotational locking means is effected by the actuator. A solenoid-operated claw is disposed alongside the actuator cam for engaging a locking formation of the actuator to secure the actuator in engagement with the actuator cam to maintain the electrical contact arrangement in a power supply ON condition. The actuator has lateraly-spaced limbs insertible between the actuator cam and the anti-rotational locking means axially to space same apart, and (ii) engageable with the actuator cam to rotate same axially to move the rod to operate the electrical contact arrangement. It also has a locking formation engageable by the solenoid-operated claw to secure the actuator in engagement with the actuator cam to maintain the electrical contact arrangement in the power supply ON condition.

摘要： A latch mechanism is disclosed for latching a cash drawer of a data terminal device in a closed position and for generating an electrical signal indicating the position of the drawer within the terminal device. The latching mechanism includes a rotatable latch member having a latching portion normally positioned out of the line of movement of a drawer catch member. Movement of the drawer to a closed position results in the catch member engaging and rotating the latch member wherein the latching portion is moved into a latching position with the catch member allowing a blocking member to hold the latch member in the latched position, the blocking member operating a switch for generating an electrical signal indicating the latching of the cash drawer.
