Out of stockToggle Switch SPDT 3 leg High Quality On-Off
[Mechanical Switches] The Mini SPDT Toggle Switch is a compact and reliable mechanical switch designed for electronic and industrial applications. It features a Single Pole Double Throw (SPDT) configuration with three terminals, allowing users to control two different circuits manually. In addition, the switch supports both AC and DC switching applications, making it suitable for a wide variety of electronic projects. It can handle up to 3A at 250VAC and 6A at 125VAC, which ensures stable performance in low-power control systems. Because of its compact body and durable metal lever, the switch is easy to install in control panels, enclosures, and DIY electronics projects. Furthermore, the included mounting nuts and locking washer help secure the switch firmly during operation. Unlike push-button switches, this toggle switch stays in its selected position mechanically. Therefore, it is ideal for power control, mode selection, and manual switching operations. Moreover, the simple 3-pin design allows easy wiring for beginners as well as advanced users. As a result, the switch is widely used in robotics, amplifier systems, automation projects, battery systems, and industrial control panels. 🔹 Key Features SPDT (Single Pole Double Throw) switch 3-pin ON/OFF toggle mechanism Supports AC and DC applications Compact miniature design Durable metal lever construction Easy panel mounting installation Stable and reliable switching operation Includes mounting nuts and locking washer 🔹 Technical Specifications Parameter Specification Switch Type SPDT Toggle Switch Operation ON/OFF Number of Pins 3 Pins Mounting Hole Diameter 6mm Rated Current 3A @ 250VAC Rated Current 6A @ 125VAC Mount Type Panel Mount Switch Mechanism Mechanical Toggle 🔹 Applications This toggle switch is suitable for many electronic and industrial projects, including: DIY electronics projects Robotics systems Audio amplifier panels Industrial control systems Power switching circuits Mode selection applications Automation projects 🔹 Wiring Information Center Pin → Common Terminal Side Pin 1 → Output/Input 1 Side Pin 2 → Output/Input 2 This Toggle switch just work as mechanical relay you need to connect the common terminal to the application you need to control and two remaining terminals to the controlling inputs. 🔹 Package Includes 1 × Mini SPDT Toggle Switch Mounting nuts and locking washer
TTP223 Touch Key Module
[Sensors, Touch Sensors] The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. An onboard LED will give a visual indication of when the sensor is triggered. When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output. TTP223 Capacitive Touch Sensor Module. The TTP223 is a touchpad detector IC replicating a single tactile button. The TTP223 is a touchpad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button key with diverse pad size. Trigger-setting mode: (1- > Short ; 0- > No Short) AB=00: No-lock High TTL level output; AB=01: Self-lock High TTL level output; AB=10: No-lock Low TTL level output; AB=11: Self-lock Low TTL level output; Connection Diagram: Features : Supports momentary or latching/toggle modes. Supports Active High or Active Low output signal modes. Dimensions : 15mm x 11mm. Input Voltage : 2 Volt – 5.5 Volts DC. The response time max ~ 60mS in fast mode, ~220mS at low power mode @VDD=3V. Sensitivity can adjust by the capacitance(0~50pF). Have two kinds of sampling length by pad option(SLRFTB pin). Stable touching detection of the human body for replacing traditional direct switch key. Provides Fast mode and Low Power mode selection by pad option(LPMB pin). Provides direct mode、toggle mode by pad option(TOG pin). Open drain mode by bonding option, OPDO pin is open drain output, Q pin is CMOS output. All output modes can be selected active high or active low by pad option(AHLB pin). Have the maximum on time 100sec by pad option(MOTB pin). Have external power-on reset pin(RST pin). After power-on have about 0.5sec stable-time, during the time do not touch the keypad, and the function is disabled. Auto calibration. Re-calibration period is about 4.0 sec when the key has not be touched. Package Includes : 1 x TTP223 TOUCH KEY MODULE
