Are Bath Heater Switch Base Boxes Standardized?

The number of small electrical appliances used in daily life is increasing, which means more switches are needed. The installation of switches requires junction boxes, which can better protect electrical safety. Are there standardized junction boxes for bath heater switches?

Are Bath Heater Switch Base Boxes Standardized?

The junction boxes for bath heater switches are indeed standardized, with common types being the 86-type and 120-type. The dimensions of the base shells for each model are unified, and the spacing for the installation screws is also standardized, ensuring compatibility. During installation, the regular switches are typically placed outside the bathroom door, while the bath heater switch is installed inside, making it convenient to use. A set of switches outside the door can serve as the main switch for the bath heater. Generally, the panel of the bath heater and the 86-type socket can be used with the same junction box.

What are some tips for buying switches?

1. Visual Inspection: Generally, high-quality products have a smooth appearance, free of burrs, and a shiny finish. Their materials are usually made of ABS or PC, which have good flame resistance and durability. If the surface looks oily but the color is pale and the texture is rough, this material has poor flame resistance. A fire test can be conducted; if the flame goes out immediately, the plastic is good; otherwise, it is poor.

2. Physical Inspection: Press the switch directly. Good products have panels that cannot be easily removed by hand and require specific tools. For lower-tier products, the cover may be easily removed. Press down one corner with the thumb while holding the opposite corner, and if the panel flexes or feels loose, the product's quality is poor. Conversely, if it maintains its form, the quality is reliable.

3. Auditory Inspection: Gently press the functional components of the switch; high-quality sliding switches produce quieter sounds, have a smooth feel, and consistent rhythm. In contrast, a switch that has a harsh or broken sound when toggled indicates poor quality.

4. Voltage Selection: Switches and sockets must be chosen according to the working current of the electrical products and lighting fixtures. Since the switch controls the lighting, the rated current of the switch must exceed the total current of the lights it controls. A 16A switch is a safe choice.
