A switch is locked in position on a support so that it requires a tool for removal. This provides that the safety of the switch can not be inadvertently removed from its support. A switch 1 includes a body 2 having a T-shaped portion 3 on its upper surface 4 with a lever 5 mounted on the upper end of the T-shaped portion 3 for operating a switch (not shown) within the T-shaped portion 3. The body 2 has a pair of resilient fingers 6, which are cantilevered, mounted on the upper surface 4 on opposite sides of the T- shaped portion 3. Each of the fingers 6 has a round pin 7 on its upper surface. When the switch 1 is to be mounted on a mounting bracket 8, the fingers 6 enter into grooves 9 in the mounting bracket 8.
