摘要： A system and method according to various embodiments can include a universal contact input status detection circuit. A voltage source wets a contact with a wetting voltage. A current mirror circuit is connected across an input of the contact to provide a constant wetting current over a wide input voltage range. The input voltage can be varied over a range wide enough to include both AC voltages and DC voltages. The current mirror circuit maintains the constant wetting current during varying wetting voltage inputs across the input of the contact. A wetting voltage sensor senses the wetting voltage provided to the contact so that the status of the contact can be determined.

摘要： A method and an electronic circuit for regenerating an electrical contact are provided in order to remedy the problem of electrical contacts becoming highly resistive over time. Electrical contacts become highly resistive over time, particularly when the contacts are thermally highly stressed and/or exposed to corrosive gases. To remedy this undesired effect and to reestablish the low resistance of the contacts, an electrical regenerating signal is applied to these contacts.

摘要： According to the switch of the present invention, a lubricant containing a base oil, a soft resin polymer, and a surface active agent is applied between a fixed tab and a contact strip that undergo sliding operation in response to vertical movement of an operating part. The soft resin polymer of the composition works effective in minimizing wear of the contacting surfaces of the fixed tab and the contact strip. At the same time, including the surface active agent in the composition can prevents the lubricant from flowing to an undesired section. The lubricant with the composition above can provide a switch with a reliable switch-on/off operation.

摘要： A rotary switch is mounted in a housing having a hollow interior. The rotary switch includes a shaft, which rotatably extends through a male threaded mounting. The rotatable shaft defines a bore which extends from an inlet defined on an exterior surface of the shaft, through a length of the shaft. The bore communicates with an outlet defined in the exterior surface of the shaft. The outlet is disposed within the hollow interior of the housing, while the inlet of the bore is positioned external to the housing. The bore defines a passageway within the body of the shaft through which a cleaning fluid may pass. The inlet of the bore is covered by a knob which is removably secured to the shaft. A first contact is connected to the rotatable shaft. A second contact is disposed within the interior of the housing for contacting the first contact. The first contact is also disposed within the interior of the housing. The bore may be used in cleaning the contacts positioned within the interior of the housing. To clean the first contact and the second contact, the knob is removed and a tube, connected to a pressurized canister is inserted into the bore. Fluid from the canister passes through the bore and over the first contact and the second contact thereby cleaning them.

摘要： A low power consumption switch interface circuit (100) includes a current source (109) for providing switch current (144) having a magnitude dependent on a state of a current range signal (135). An input terminal (142) is provided to conduct the switch current (144) to an external switch (102). A circuit (101, 103, 119) for detecting a signal (141) present at the input terminal (142) provides a measured pulse (127) when the signal (141) is detected. A current range selector (129), coupled to the current source (109), outputs a first state of the current range signal (135) while the measured pulse (127) is outputted from the circuit (101, 103, 119), and a second state of the current range signal (135) while the measured pulse (127) is not outputted from the circuit (101, 103, 119). The current source (109) provides the switch current (144) at a first magnitude responsive to the first state of the current range signal (135), and a second magnitude responsive to the second state of the current range signal (135).
