Overview

The Vimar VM00900 is a 1-pole normally closed (NC) push button rated 250 V AC and 60 W (0.24 A), with screw-type pillar terminals and a white finish with a matte surface.

Because it is normally closed, the circuit stays closed at rest and opens when you press the button. That behavior is commonly used for control and interlock functions on board, including refrigerator control circuits where a button press needs to interrupt the circuit.

It fastens with screws and uses a shallow 10 mm built-in depth, which helps when you are working in tight helm, galley, or locker panels.

Key features

• 1-pole, normally closed (NC) push button action
• Rated 250 V AC, 60 W (0.24 A nominal)
• Screw-type pillar terminals for straightforward terminations
• Screw-mounted fastening with 10 mm built-in depth
• Non-illuminated button with no imprint for simple panel labeling
• Halogen-free thermoplastic body with a matte surface

Installation and wiring

Keep the switched circuit within the 60 W rating at 250 V AC. For anything that draws more than that, use the button to switch a relay, contactor, or control input instead of feeding the load directly through the contacts.

Terminate conductors fully under the screw terminals, then support the wiring so vibration or a tug on the cable cannot work the connection loose. Always isolate shore power and inverter feeds before opening an AC panel.

Materials and placement

The thermoplastic housing suits interior electrical spaces. Mount it where it stays out of washdowns and spray, and keep the back of the unit away from areas where condensation can collect.

Use on board

This push button suits refits where you need a compact NC momentary contact for a refrigerator circuit, a safety interlock, or a service stop function in a small control box. It also works well when you are standardizing controls across a boat and want a consistent look in white.
