For the mechanical timer that Jaye make have 15minutes, 30 minutes, 60 minutes, 90 minutes and 120 minutes, no matter which minutes, the general size and specifications of the timers are almost same, all of them can chosen to be with alarm bell or without alarm bell, and the working angle and shaft shape and length can be selectivity.
All the oven mechanical timers that made by Jaye must meet the below basic standards:
1) Appearance quality:
No obvious corrosion is allowed on the metal surface, and the coating shall be free of exposed bottom, peeling and blistering.
The surface of non-metal should be smooth, not allowed to have cracks, obvious foam, deformation and burr.
2) Working reliability:
The timer shall work reliably and be able to switch the power supply normally. In addition, it can ring once at the end of the timer.
3) Working torque:
The general operating torque of the timer shall not be greater than 0.5N * M.
4) Strength of spindle limit device
At a torque of less than 0.8N * m, the spindle limit device shall not be deformed or damaged.
5) Insulation strength:
The insulation resistance between the live parts of the timer (current carrying parts of the timer) and the accessible non live metal parts shall not be less than 100m Ω.
6) Electrical strength:
For the section between the live part of timer and the accessible non live metal part, it can withstand the voltage test of 1800V (effective value), 50Hz frequency for 1 minute, and there is no insulation breakdown and flashover phenomenon.
7) Heat and humidity resistance:
After the damp heat test according to GB / T 2423-3, the timer shall meet the following requirements:
a). The insulation resistance shall be no less than 10MΩ;
b). it can withstand the 1800V (effective value), 50Hz frequency voltage test for 1min, with no insulation breakdown and flashover.
