転用することはできない。 In such reed switches, reducing the amount of contact wear is necessary to extend the life of the switch, but the type of wear has a greater influence on the life of the contacts than the amount of contact wear, and the type of contact wear depends on the configuration and load of the reed switch. Depends on conditions. Therefore,
The one for AC110V that has been used conventionally,
It is not possible to convert to AC220V, or convert a 220V AC product to AC110V.

and the sealed gas 5 sealed in the insulating tube 4.

Rh is applied to the contact part of lead pieces 2 and 3 consisting of the remaining Fe.
Layers 2a and 3a are deposited, and the filler gas 5 is N2 gas.
It was 0.75±0.25 atm or Ar gas 0.5±0.2 atm.
On the other hand, the normally open type for AC220V generally uses the same lead pieces 2 and 3 as the lead pieces for 110V, and the sealed gas 5 is N 2 gas at 1.5±0.5 atm.

いる。 On the other hand, in a device that can be connected to either a 110V AC or 220V AC commercial power source, a reed switch for opening and closing the power supply circuit is required to have a contact life for both 110V AC and 220V AC. However, the reed switch for AC110V, which has a conventional configuration,
Using 220V AC is extremely difficult because the usage conditions are too severe compared to the intended conditions. Therefore, the above-mentioned AC220V reed switch whose contact part is coated with Rh has been used for the dual purpose, but for example, it can be used for AC110V/1A or AC220V/
The contact life when used at 1A is less than 200,000 times and about 100,000 times, respectively, and improvements are desired.

る。(d) Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned problems, and the present invention proposes that the life of the Rh contact to which AC110V is applied in a N2 gas atmosphere is shortened by arcing,
The lifespan of Rh contacts applied with AC220V in a gas atmosphere is reduced due to glow discharge, and when only N2 gas or
Reed switch filled with Ar gas only
Although using a dual-purpose switch for AC110V and 220V includes inappropriate factors, N2 and N2 , which have different consumption types,
We focused on the fact that the lifespan would be longer than conventional ones by mixing Ar with Fe (2 to 13%) - Co (remaining), which has a lower resistance than 52 alloy.
This invention was developed with the focus on the fact that the lifespan can be extended by creating lead pieces that are joined together.

However, the pressure of the filled gas (Ar-N 2 ) 5 was set at 1.5±0.5 atm in consideration of the reed switch that has been put into practical use.
The insulating tube 4 was made of glass for nibcolloid, which can be fused to the lead pieces (Fe--Co) 2 and 3.
