Description

The PBS-11B is a compact, momentary push button switch engineered for industrial control and automation applications. Its SPST (Single Pole Single Throw) contact configuration provides a simple, reliable on/off signal path, activated by pressing the 12mm red button. The switch is housed in a robust body designed for panel mounting via an 18mm hole.

With a robust electrical rating of 250V AC and 3A, this switch is suitable for controlling a wide range of industrial loads directly or through relay circuits. The momentary action ensures the circuit is only closed while the button is depressed, making it ideal for start functions, reset operations, or user input interfaces in machinery, test equipment, and custom control panels.

Key Features

  • High-current SPST momentary contact mechanism rated for 250V AC / 3A.
  • Red 12mm lock-style push button provides clear visual status and tactile feedback.
  • Designed for panel mounting with an 18mm mounting hole diameter.
  • Durable construction with a high-precision mechanism for reliable, long-life operation.
  • Simple 2-pin terminal connection for easy wiring and integration.
  • Compact form factor suitable for space-constrained control panels and enclosures.
  • Optimized performance-to-cost ratio for industrial and prototyping applications.

Applications

  • Industrial control panel start/stop and reset functions.
  • Machinery and equipment operator interface stations.
  • Prototyping and custom electronic project user input controls.
  • Test and measurement equipment manual trigger switches.
  • Safety interlock or emergency stop circuit activation (as part of a safety-rated system).

Frequently Asked Questions

What is the electrical rating of the PBS-11B push button switch?

The PBS-11B switch is rated for 250 Volts Alternating Current (AC) at a maximum current of 3 Amperes. This rating makes it suitable for controlling small motors, solenoids, relays, or indicator lights in industrial and commercial control circuits.

How do I mount this switch onto a panel or enclosure?

This switch is designed for panel mounting. You need to drill an 18mm diameter hole in your panel. The switch body is inserted from the front, and it is secured from the rear with the included nut. Ensure the panel thickness is compatible with the switch's mounting thread length.

Is this a momentary or latching switch?

This is a momentary action switch, specifically SPST-NO (Single Pole Single Throw, Normally Open). The circuit is closed only while the red button is being pressed and held down. Upon release, the contacts open and the circuit is broken. It is not a latching or maintained-contact switch.

What is the purpose of the 'lock' style on the red button?

The 'lock' style refers to the physical shape of the red button actuator, which is commonly associated with emergency stop or important function switches. It provides a distinct tactile feel and visual prominence, making it easily identifiable by an operator, but it does not mechanically latch the switch in the pressed position.
