Dimmer Light Switches

Please choose from the dimmer light switch selection below - categorised by colour and plate design. Please click on each category to view the full range of styles and insert types:

Our dimmer switches are available with 250w, 400w and 1000w load ratings. 250w dimmers have a minimum working load of 40w, 400w dimmers have a minimum working load of 50w and 1000w dimmers have a minimum working load of 150w (and are suitable for 700w low voltage VA). Underloading a dimmer switch (not meeting the minimum load) can result in buzzing, overheating, lack of dimming capability and possible dimmer switch failure.

All G&H dimmer light switches are operated by a push on / push off rotary control dimming knob. When you switch the dimmer on, the lights will resume at the same level as when they were switched off. The lights can then be dimmed up or down using the rotary control dimming knob.

G&H dimmer light switches are suitable for both mains and low voltage circuits, up to the maximum load as specified on the dimmer. They have a soft start feature and are ideal for use with mains incandescent GLS lamps (standard mains light bulbs). G&H dimmers can also be used with GU10 or similar Hi Spot Mains Halogen lamps (but these lamps must incorporate an internal fuse).

All G&H dimmer light switches are 2 way. This means they can be used either on their own, or in combination with another switch to create a 2 way circuit (2 switches working together to control the same light circuit). Dimmers are available as 1 gang, 2 gang, 3 gang and 4 gang. Each gang will control an individual circuit and has a maximum load as specified on the dimmer (e.g. a 4 gang 400 watt dimmer switch can control 400 watts per gang).
