Abstract: 1536610 Protective circuits GILLETTE CO 8 March 1977 [8 March 1976] 09782/77 Heading H2K and H2H A hand held appliance for connection to an A.C. source having a line conductor and a neutral conductor comprising a housing having a contact portion 17, means 18, 19 for measuring the impedance of an operator with respect to the line or neutral conductor of the A.C. source when the operator touches the contact portion, and switch means 45 for disconnecting the appliance from the live conductor when the impedance is below a predetermined level. If the impedance is acceptable, the signal at 26 is above ref. 1 applied to comparator 34 but below ref. 2 applied to comparator 36 so that the appliance is switched on at 45. If the impedance with respect to live or neutral respectively falls, the signal at 26 falls to below ref. 1 or rises above ref. 2, and switch 45 is opened. On initial connection of the appliance to the A.C. source, a high signal occurs at 26, and switch 45 remains open. The operator momentarily opens switch NC so that the signal at 26 falls between ref. 1 and ref. 2 and switch 45 closes. Providing plug 23, 24 has been inserted the correct way round, a potential appears at the touch grid such that the signal at 26 is maintained between ref. 1 and ref. 2, and switch 45 remains closed. If the plug is the wrong way round, there is only a small potential at the touch grid, and the signal at 26 falls below ref. 1 causing switch 45 to open.
