ABSTRACT:
A switch (12, in FIG. 1) for mounting on a circuit board (P), has a minimum number of parts and a very small height. The switch includes an insulative support (29) for lying on the circuit board and a switch element (33) with a pedal (58) extending above the upper face (18) of the support to be downwardly deflected by a card as the card reaches its fully installed position. The switch element is formed of electrically conductive sheet metal material, with a connect tab (43) for permanently engaging a first switch trace (25) on the circuit board, and with a contacting part (44) for lying over a second trace (26) on the circuit board. When the pedal is depressed, it also depresses the contacting part (44) to press it against the second trace to thereby close the switch.
