Switches in miniTesla: build electronics and more

This board allows you to build a neat little toggle switch. Additionally to the printed circuit board, you will receive an M4 brass screw, an M4x20 mm long nylon hex spacer, a 3-hole long trace, and two M4 screws with nuts. You will also need three spring contacts (not included in this kit) to connect the switch to your circuit.

This is a rotary switch that connects a common (COM) pin with one out of 9 pins. This is a through-hole component and thus this sub-board can only be used on the edge of a pegboard, either immediately above or below the pegboard.

A momentary pushbutton. It connects the two pins only as long as the button is pressed.

Our toggle switch has three positions: left, middle, and right. The left switch position connects the middle pin to the left pin. The middle is a neutral position where the middle pin is not connected to anything. In the right position, the middle pin is connected to the right pin. You can use this toggle switch as a simple on-off switch, or as a selector between two alternatives.

A potentiometer, or variable resistor, with three pins labeled CW, CCW, and wiper. The wiper moves between the CW (clockwise) and CCW (counterclockwise) endpoints and therefore the resistance between the wiper and the endpoints changes with the position of the potentiometer. The resistance between CW and CWW is a constant 10k Ohm.

Additionally, this potentiometer has a built-in momentary pushbutton by pressing down on the dial. When pressed the SW1 and SW2 pins are connected.
