Servo Control for Model Railway Points

Servo control is a compact, flexible way to operate model railway points, signals and animated accessories. CMMME supplies the electronics, servos and support needed to build reliable DCC or push-button control.

Control points, relays and LEDs together

The CMMME Prima DCC decoder can control up to 32 outputs for servos, LEDs and relays. That means a single command or button can move a point, switch track polarity and update a control panel indicator at the same time.

Useful parts for point control

• CMMME Prima DCC decoder
• SG90 micro servos and mounting brackets
• Relay modules for polarity switching
• Push buttons and prewired LEDs
• 5V power supplies and extension leads
