Comparison of the safety of the boat switch and push button switch Many people may not understand the difference between the large ship type switch and the small button switch. It is simply a matter of aesthetics. In fact, it is not entirely true that there is a big difference in safety between them:
1. Breaking range. Due to the problem of the torque, the small button and the large ship type have the same pressing range, and the large ship type switch can give the moving part a larger breaking range. If the small button switch is to achieve a similar breaking range, the internal spring will have a higher twist than the large ship type, which is more prone to problems. It is often seen that the small button switch is stuck, largely because its internal spring has passed its service life.
2. The number of wires is limited. Since the small buttons occupy less panel space, many brands of small buttons will provide more than 4 switch specifications, up to 6 digits. The corresponding switch will be connected to a very large number of wires at the rear (if it is a 6-position dual-control switch, 12 wires will be connected at the rear). Excessive wires are filled with the cassette, and on the one hand, heat dissipation becomes a big problem. On the other hand, the wires are easily tripped, causing accidents such as open circuit, short circuit, and electric leakage. Large ship type switches are generally less than 4 digits, and branded products often have a maximum of three digits, which also limits the number of wirings at the rear, ensuring sufficient space in the cassette.
3. Reduce the risk of electric leakage during use. The small button switch is generally only the size of the finger. If the user's hand is in a wet state (such as a bathroom), the finger and the button are in full contact, and the gap between the button and the panel is also contacted. If the quality of the switch is poor, it may cause the internal conductor of the switch to contact the water and leak electricity, posing a threat to the user. The large ship type switch has a large pressing space, which reduces the risk in this respect.
