LA2 Momentary Push Button Switch – Red & Green, 30mm Panel Mount

The LA2 Momentary Push Button Switch is a reliable, self-resetting flat-head switch designed for a wide range of industrial and consumer circuit control applications. Available in both red and green, this iron-bodied switch fits a standard 30mm panel mounting hole and delivers a rated contact capacity of 5A at 250VAC, making it a versatile choice for workshops, machinery panels, electronics projects, and more.

Made in Mainland China.

Key Features

• Momentary (Self-Resetting) Action: The switch automatically returns to its default position upon release, providing a temporary circuit state change — ideal for pulse-triggered control signals.
• 30mm Mounting Hole: Fits standard panel cutouts for easy installation in enclosures and control panels.
• 5A / 250VAC Contact Rating: Handles both AC and DC low-voltage circuits with confidence.
• Flat Head Design: Flush profile keeps panels clean and reduces accidental activation.
• Durable Iron Construction: Built to withstand repeated use in demanding environments.
• Available in Red & Green: Color-coded for intuitive start/stop or on/off labeling in control systems.

Frequently Asked Questions

Q: What does "momentary" or "self-resetting" mean for this push button switch?

A: A momentary push button switch only changes the circuit state while the button is physically pressed. Once you release the button, it automatically springs back to its original position (self-resets). This is ideal for applications like doorbells, relay triggers, PC power switches, and short-pulse control signals where you only need a brief circuit connection.

Q: Can this LA2 push button switch be used as an emergency stop button?

A: No. This switch is not a positive-break type, which means it does not guarantee forced contact separation and does not meet safety standards for emergency stop (E-stop) applications. For E-stop functions, always use a dedicated, certified positive-break emergency stop switch.

Q: What panel hole size is required to install this switch?

A: This LA2 push button switch requires a standard 30mm (1.18 inch) panel mounting hole for installation. The overall body dimensions are 40 × 40 × 38mm, so ensure adequate depth clearance behind the panel.

Q: Is this switch suitable for both AC and DC circuits?

A: Yes. The LA2 switch is rated for 5A at 250VAC and is also compatible with DC circuits within the 3C rated voltage range of 36V and below. Always ensure your circuit's voltage and current requirements are within the switch's rated capacity before installation.
