Abstract: A push-button switch test device having a flexible tab fixedly attached to a pushing member. The flexible tab is made of a flexible material and includes a deformation sensitive resistor mounted on a surface. The push-button switch test device may be used to test a push-button by imposing a known force on the flexible tab while receiving a signal level across the deformation sensitive resistor.

Configurations of a plurality of push-button switch test devices may be arranged in a test frame that mirrors a configuration of push-button switches.
