SWITCH DEVICE

PROBLEM TO BE SOLVED: To provide a switch device reducing costs of a switch with a locking function and a limit switch. SOLUTION: The switch device comprises a switch body 1 made up of a microswitch; a push button 3 for operating a lever 14 to depress and operate an actuator 15 of the switch body 1; and a case 2 for holding the switch body 1 and the push button 3, as a basic configuration. To design the device to be a switch with a locking function for locking an object that opens/closes such as a door or a cover in a closed state so as not to be easily opened when the object is closed and for detecting the opening/closing of the object, the device is assembled with a permanent magnet 4 and a yoke 5 disposed in the case 2, in addition to the push button 3 and the switch body 1. To design the device to be a limit switch, an end of a lever 7 is pivotally attached to a rotating shaft 21 formed in the case 2. COPYRIGHT: (C)2005,JPO&NCIPI
