Abstract
The utility model provides a dual-power change-over switch, and a commonly-used microswitch and a standby microswitch are used to control and operate a commonly-used circuit breaker and a standby circuit breaker, replacing a commonly-used auxiliary switch and a standby auxiliary switch used in an existing dual-power change-over switch. Since the angles of adjustment sheets of the microswitches are easier to adjust accurately compared with the auxiliary switches, the switching accuracy of the whole dual-power change-over switch can be improved. In addition, since the microswitches are relatively small in size, the occupied installation space is relatively small, and not many other components are involved in installation processes of the microswitches, and when the microswitches are installed and adjusted, other components of the dual-power change-over switch needn't be dismounted, so that the difficulty of installation and adjustment of the dual-power change-over switch is greatly reduced compared with an existing dual-power change-over switch.
Description
Technical field
