Claims

[Scope of utility model registration request]

A crossbar that opens and closes the contacts of the switch by rotation;
An operating device for an electric switch comprising a crossbar drive rod that rotationally drives the crossbar, and two springs for opening and closing that give movement to the crossbar drive rod,
The opening and closing springs are compression coil springs and are configured as a spring unit arranged concentrically around the crossbar drive rod, and both the opening and closing springs are loosely fitted to the crossbar drive rod. a spring unit holder that abuts one end and is moved on the crossbar drive rod by an energy storage l/bar; and a closure that is fixed to the crossbar drive rod so that its position can be adjusted and abuts the other end of the closing spring. An operating device for an electric switch, comprising: a spring support; and a frame fixing portion that supports the other end of the opening spring.
