Pushbutton Switches

TP21MS9CBE application field and working principle

The TP21MS9CBE is a normally open medium-duty pushbutton switch manufactured by Carling Technologies. It is rated for AC and DC voltage and current, and can handle a wide range of application from safety circuits to PC Board and instrument switches. It utilizes a momentary-on/off remote switch with a built-in adjustable momentary-on delay and circuit break timing for energy efficient switching. The switch has an aesthetically pleasing body with a chrome-plated plastic actuator, and is available in momentary and latching versions.

The TP21MS9CBE has an operating temperature range of 40-90°C and a voltage of 125VAC/DC. Its current rating is 0.5A at 125VAC, and 0.1A at DC. The switch is IP67 water resistant and suitable for both front panel and board mounting. It has a standard contact arm of 19.2mm long and a contact gap of 1.00mm at full travel.

The TP21MS9CBE is used in a wide range of applications including the control of lights, security systems, pumps, motor machines, automatic doors, emergency switches, and other electronics. The device has a simple, quick installation process and requires minimal maintenance. It is designed to offer reliable performance, long-lasting durability and easy operation in almost any type of environment.

The switch works by creating an electrical circuit when the actuator is pushed. When the actuator is released, current flow is interrupted and the circuit is open. This allows the switch to be used as a latching or momentary switch depending on the configuration of the circuitry. Also, the switch has a built-in adjustable momentary-on delay which helps to ensure proper operation of the switch.

The TP21MS9CBE is a reliable and economical switch for a wide range of applications. It offers excellent performance, easy installation and operation, and long-lasting durability. The switch is suitable for outdoor as well as indoor applications, and is IP67 water resistant. It is an ideal choice for safety circuits, instrument switches, PC board and other electronic applications.
