Data Entry Keypad
A low profile 3 x 4 keypad of compact size suitable for use on hand held and other small equipment. A single
rectangular cut is required to fit the keypad through the front panel and four mounting holes are required for the
retention of the keypad. The conductive rubber contacts require a low operating force, but have a positive action to
give the operator feedback. Connections are terminated to solder pads on the PCB at the lower edge of the switch.
