摘要： There are provided, together with two microswitches 20 accommodated in a cylindrical compartment 13, a manipulation member 2 which can freely swing about a pivot portion 2a in the directions of arrows A and B, a transmission member 3 which can freely move in reciprocating motion within a specific range between a transmitting position and a non-transmitting position located along a radial direction of an arc which is the trajectory of the swing motion of the manipulation member 2 in the directions of the arrows A and B, a contact member 4 which can freely move in reciprocating motion within a specific range between an exposed position and a retracted position in the directions of arrows E and F, a driven member 5 which can freely move in reciprocating motion in the directions of arrows G and H, and a restricting part 6 fixed at a position opposing the contact member 4. The swing motion of the manipulation member 2 in the direction of the arrow B up to a point where the manipulation member 2 goes into contact with the restricting part 6 is transmitted to the microswitches 20 via the transmission member 3 and the driven member 5, and the swing motion of the manipulation member 2 in the direction of the arrow B is not transmitted to the microswitches 20 after the contact member 4 has gone into contact with the restricting part 6. This arrangement makes it possible to achieve improved operability of an enable switch, enhanced safety with the provision of multiple contact mechanisms, and easier installation of the enable switch on a portable operator panel.
