MTS-123 Lever Switch SPDT ON-OFF-ON 3 Wires 3 Pins 5A 125VAC 2A 250VAC (ON) -OFF- (ON)

Description

The MTS-123 SPDT ON-OFF-ON lever switch is an electronic component that allows interrupting and restoring the flow of electrical current in a circuit. It features a lever with three positions: ON, OFF, and ON, enabling multifunctional control over device or circuit power supply. Features Type: SPDT (Single Pole Double Throw) Positions: ON-OFF-ON Wires: 3 Terminals: 3 Maximum Current: 5A at 125VAC, 2A at 250VAC Maximum Voltage: 125VAC, 250VAC Lever Size: 6mm What it’s for The MTS-123 lever switch is ideal for Arduino and general electronics projects. It allows creating multifunctional controls in applications such as 3D printing, adjustable home lighting, and circuit management. It can be used to connect LEDs to relays, control access to circuits or manage the power supply of electronic devices based on the lever’s position. Tutorial: How to use MTS-123 Lever Switch The MTS-123 lever switch is an essential component for electronics and Arduino projects. It serves to control and block electrical circuits, ideal for beginners and home projects. What you need Arduino Uno or compatible connection cable circuits to be controlled Steps Check the voltage and current of the circuit to ensure compatibility with the switch (check datasheet) Connect the circuit to be controlled to the ON contacts of the switch Connect the switch to an input pin on the Arduino Write a sketch to control the state of the switch Test the circuit Example code void setup() { pinMode(2, INPUT); } void loop() { int buttonState = digitalRead(2); if (buttonState == HIGH) { Serial.println(“Switch ON”); } else { Serial.println(“Switch OFF”); } } Mini-project Create a controllable home lighting system with the lever switch. Connect an LED to a relay and control the relay with the switch. Common mistakes Connecting the circuit to an incompatible voltage or current Omitting pull-up/pull-down resistors Using an output pin instead of an input pin to read the state of the switch Not testing the circuit before using it in a larger project Recommended accessories Relay Module Breadboard LED 10kΩ Resistor Frequently Asked Questions Where can I find the datasheet? The datasheet is available on the manufacturer’s website or our store.
