Mechanical Touch Switch D5B

• Slow-action switching mechanism used.

• Gold-plated contact with coil spring capable of switching micro current/voltage load while providing high contact reliability.

• Inputs directly to microcomputers and programmable controllers.

• Three sizes (M10, M8, and M5) and three types of compact actuators.

• Easy panel mounting.
