Take the switch out of the pedal cover.
Connect both leads to the switch contact pins. The meter should indicate a
short circuit.
When pressing the switch acturator (small pin near the screw thread of the
switch) the meter should read infinite ohms.
If this does not happen, the switch is defect. Maybe the actuator is stuck
and this maybe solved with some cleaning solvent and/or light oil. Use
pliers to do this.
Cheers
Hans

I used an ohm meter on my switch and nothing registered on the meter when I
touched the wire and the tip of the switch so I take it that it's bad?
