Built-in access switch PNI PB101, NO/COM output contact, max 36V 3A, white

Built-in access switch PNI PB101 is a compact flush-mounted switch with a normally open (NO) / common (COM) contact. It is designed for integration into access control panels, doors, or enclosures where a simple electrical interface is required for unlocking, signalling or monitoring. The switch supports low-voltage systems and is suitable for installations that need a discreet, white-colored flush actuator that blends with standard interior fittings.

Advantages

The PNI PB101 offers a small footprint and a flush-mounted design that reduces protrusion and risk of accidental activation. Its NO/COM contact provides a straightforward electrical interface compatible with a wide range of access control and alarm systems. Rated for up to 36 V and 3 A, the switch supports common low-voltage circuits while maintaining reliable mechanical action and stable contact performance over repeated cycles.

Suitable for

• Access control panels and door release circuits
• Alarm system inputs and tamper detection
• Cabinet or enclosure door monitoring
• Automated entry setups and gate control interfaces

Key specifications

• Contact configuration: Normally Open (NO) / Common (COM)
• Maximum rated voltage: 36 V (low-voltage systems)
• Maximum rated current: 3 A
• Mounting type: Flush / built-in mounting for panels, doors or enclosures
• Color and finish: White flush actuator

How to use

Install the PNI PB101 into a prepared cut-out on an access control panel, door frame or enclosure, ensuring the actuator is flush with the surface. Connect the NO and COM terminals to the corresponding input or control circuit of the access control or alarm system, following the system wiring diagram and local electrical safety rules. Verify the switch operation by actuating the device and observing the control system response; ensure voltage and current applied do not exceed the specified maximums.

Usage recommendations

Use this switch only within the rated voltage and current limits and in dry indoor locations or protected enclosures. For reliable long-term operation, avoid subjecting the actuator to excessive mechanical force or impact. When integrating with alarm or access systems, test wiring and logic sequences after installation to confirm correct signalling and fail-safe behaviour.
