Above switches are SPDT but may be used as SPST. 25 Amp switch available on codes 4, 5, & 6 only.
For dry circuitry, i.e. 5VDC·50 rnA or less, use gold contact switch (Code .1 or 1). If less than 20mA, performance of electrical swtich will be environmentally dependent. II there is some form of contamination (dust, dirt, oil, chemical residue, etc.) at point of contact, the electrical switch could perform intermittently, as there would be Insu icient current to burn o any possible contamination.
