[0031] The utility model also provides an auxiliary switch, comprising the switch bracket 1 described in any of the above embodiments, at least one of the switch mounting areas 11 is provided with a micro switch 3, the button 31 of the micro switch 3 faces the touch plate 2, see Figure 4 and Figure 5 As shown, the auxiliary switch has all the advantages of the switch bracket 1 mentioned above.

[0032] The utility model also provides a universal frame circuit breaker, including an auxiliary switch 100 mounted on a drawer seat and a trigger member 5 mounted on a main shaft 4 of an operating mechanism of a circuit breaker body. The drawer seat and the circuit breaker body are not shown in the figure. The auxiliary switch 100 adopts the auxiliary switch described in the above embodiment, such as Figure 6 and Figure 7 As shown, the trigger member 5 includes a hollow sleeve portion 51 and a contact and pressure portion 52 fixed at one end of the sleeve portion 51, the sleeve portion 51 is sleeved and fixed on the end of the operating mechanism main shaft 4, and when the circuit breaker body is installed in place in the drawer seat, the contact and pressure portion 52 is close to the driving portion 21. At this time, when the operating mechanism main shaft 4 rotates, the contact and pressure portion 52 contacts the driving portion 21 to make the contact plate 2 swing, so as to trigger the micro switch 3; the universal frame circuit breaker has all the advantages of the above-mentioned switch bracket 1 and auxiliary switch.
