Abstract

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.

Safety Lock-In Switch

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. Each of the grooves 9 has a ramp to deflect the pins 7 on the fingers 6 downwardly as the switch 1 is moved towards a wall 10 of the mounting bracket
8. As a result, the pins 7 pop into round holes 11 in a surface 12 of the mounting bracket 8 to lock the switch 1 to the mounting bracket 8. Removal of the switch 1 from the mounting bracket 8 can be accomplished only by pushing down on the pins 7 to remove them from the holes 11. The pins 7 do not protrude beyond the surface 12 of the mounting bracket 8 so that a screwdriver or other tool must be inserted into the holes 11 to push the pins 7 downwardly to release the switch 1 from the mounting bracket 8.
