Abstract
Abstract A hold down and guard device for a push button switch, secured to a support by mounting means through which the push button projects. The hold down and guard device has a body presenting surfaces engageable with complementary surfaces on the mounting means for the switch to hold the device in a fixed position with respect to the push button and switch and has a further portion which is fixed with respect to the body and projects over the push button to hold the button depressed or to prevent it from being unintentionally or accidentally depressed. The device may consist of a single unitary element such as a metal stamping or may be provided with means on the further portion thereof movable with respect to the body into a position to actuate the switch.
